High Performance Vapour Control Layers - Polyvap

POLYVAP is a range of high performance, aluminium cored vapour control layers (VCLs) coated with a high quality polymer modified bitumen coating. The underside of POLYVAP TT & POLYVAP TS are protected by Polyflam a special polyethylene film which melts upon torching. In the POLYVAP TT version the top surface is also protected by a layer of Polyflam providing a bitumen rich surface. The top surface of POLYVAP TS has a coating of fine sand thereby enabling the use of bitumen or Polyglass polyurethane adhesive to bond insulation to the upper face of the VCL. POLYVAP SA is a self-adhesive membrane manufactured using ADESO ® technology and can be incorporated in to a completely flame free ADESO ® self-adhesive roofing system.
